I have PV and have just had an extremely quick visit to the optician after the words on my computer screen started dropping and strange things were happening with size also. I have a headache and pressure in my head. I have had visual migraines before with flashing lights, floaters, etc but this is the first time print has been affected. In the past, my vision was like looking through water for about 5 mins and then it came back again. I have had my eyes thoroughly checked and it is just down to migraines. Does anyone else experience this? It is quite scary to begin with.
